Apparent negative interference due to variation in recombination frequencies.
Variation in recombination frequencies may lead to a bias in the estimated interference value in a linkage experiment. Depending on the pattern of variation, the bias may be toward negative interference or toward positive interference, even when there is positive interference at the cytological level. In this paper we have mainly concentrated on the case of negative interference. We use models ...
متن کاملA computer program to simulate multilocus genotype data with spatially autocorrelated allele frequencies.
Many models for inference of population genetic parameters are based on the assumption that the data set at hand consists of groups displaying within-group Hardy-Weinberg equilibrium at individual loci and linkage equilibrium between loci. This assumption is commonly violated by the presence of within-group spatial structure arising from nonrandom mating of individuals due to isolation by dista...
متن کاملA general algorithm to compute multilocus genotype frequencies under various mating systems
This paper provides a general method to derive algebraic expressions of genotype frequencies for multiple loci under various mating systems, including random mating, back-crossing, selfing, and full-sib mating. For each mating system, general equations are presented. In the case of three loci, comprehensive tables provide recurrence equations for genotype frequencies under random or self mating...
متن کاملInference of population structure using multilocus genotype data: linked loci and correlated allele frequencies.
We describe extensions to the method of Pritchard et al. for inferring population structure from multilocus genotype data. Most importantly, we develop methods that allow for linkage between loci. The new model accounts for the correlations between linked loci that arise in admixed populations ("admixture linkage disequilibium"). This modification has several advantages, allowing (1) detection ...
متن کاملEvidence from Sordaria that recombination and conversion frequencies are partly determined before meiosis, and for a general model of the control of recombination frequencies.
TUDIES of the control of recombination frequencies (abbreviated “RFs” ) have several aims: to determine how genetic and environmental controls of RFs operate, to provide information on the mechanism of recombination, and to find way of manipulating RFs to suit breeding programmes. The present study concerns details of the control system and the time, or times, in the meiotic cycle at which an e...
